OmniRoute Codex SDK worker harness at Codex 0.160.0 (supersedes #551)

[seathatflowsinourveins]

Scope

• What this PR changes. It publishes the Claude-dispatched Codex SDK worker that runs through the OmniRoute gateway, refreshed to Codex 0.160.0, and supersedes stale Enhance Claude-dispatched OmniRoute workers with native MCP, agents and workflows #551 (head 0e86cb7e77, 2026-09-30, no live owner; its 2026-10-03 supersede notice passed its objection window with no objection). Contents:
  • examples/omniroute-codex-sdk/: the worker, tests, locks, enhancement kit, runtime template and graph;
  • the omniroute-runtime-worker project skill;
  • examples/claude-runtime-sdk/ and tools/runtime-worker-evidence/;
  • the 2026-09-30 decision, receipts and convergence records, carried unchanged;
  • a dated 2026-10-03 sibling record, decision and receipt.
• Base commit: 56473e4b8.
• Lane: lane:foundation. manifests/evidence.json changes by registration only, in the last commit.
• Owned paths touched. The paths above, plus .github/osv-scanner-lockfiles.json and tests/test_osv_lockfile_coverage.py (the uv script locks are listed and covered, as Enhance Claude-dispatched OmniRoute workers with native MCP, agents and workflows #551 did) and adoption/skills/lifecycle.md (a dated project-skill exception).

SOTA sources

• Codex, rust-v0.160.0 (a956835d).
  • The official Python SDK is sdk/python, openai-codex 0.160.0 with its bundled CLI.
  • The startup handling follows the SDK's thread offloading and the asyncio shield contract.
  • The curated-plugins startup gate is at codex-rs/core-plugins/src/manager.rs:743-763. The boolean features.plugins is in codex-rs/core/config.schema.json:7038.
• OmniRoute. The gateway route is cx/gpt-6.1-sol-max on loopback, at the deployed build recorded in docs/decisions/2026-09-30-omniroute-rebuild.md.

Reviews

Both reviews returned changes-needed and were repaired in one round:

• Opus evidence review:
  • Blocking:
    • Independent-review claims had no recorded run. They are now relabelled as builder self-review.
    • The limits were missing from the README and skill. They are now stated.
  • Should-fix:
    • The production plugins override was untested. It now has a test.
    • The 10-03 observations sat inside 09-30 frozen records. They now have their own sibling record.
    • The project skill had no recorded exception. It is now dated in adoption/skills/lifecycle.md.
• GPT-6.1 Sol cross-family review:
  • Should-fix:
    • A deadline during startup could report cleanup closed early. Startup is now held and settled before close.
    • The graph required an uninstalled skill unconditionally. It is now explicit task configuration.
  • Minor: the project-skill note above.
• Residuals, recorded:
  • Backend effort is not observed.
  • Writing dispatch is not qualified.
  • One MCP Transport closed failure is retained.
  • The AD-1 shared-home state-DB check belongs to Codex 0.159.3 -> 0.160.0 with the Python SDK pair: pins, qualification receipt, tests and checkpoint #626's host switch.

Findings at exact head 7c9d721, base 56473e4, from direct primary source/artifact reads. No new SDK or provider task was run.

The PR description claims the successful coordinator shell check was “re-run on the final bytes too.” The receipt instead says the repaired bytes have no new live-model run; both live_task and coordinator_shell_observation have candidate_phase before-B2-repair, the latter binds source SHA2563aa19fa790e661f5142fa316b58473e508f68af6c4f155f0a2fa469177c8a623, while final worker.py/source_closure binds33057e8b5bcb042bed8f517d759b00936767d2a8df7055dd2179df5d93ace618. b2_repair records native_model_tasks_started0. The standalone coordinator-shell-observation names a generic candidate and one private native-result hash, without a final-B2 source binding.

Please reconcile that exact scope conflict: either retain the accurate pre-B2 observation and correct the description, or hand off the existing distinct final-B2 original result with source/executable/cwd/command/time/exit/output bindings. This requests evidence already claimed, not a silent rerun. Preserve all earlier shell/MCP/startup/validation failures. Final 19-test fixture runs and metadata preflight remain their declared local integration/synthetic class; they do not establish a new provider run or complete SDK role qualification. Writing, error-free MCP transport and backend effort/identity remain open as the receipt states. No whole role-lane ACCEPT is issued by this read.

The supported source remains openai/codex rust-v0.160.0 at a956835d, sdk/python; local startup/cleanup composition and its private SDK-attribute boundary keep the receipt's declared limits. Runtime owner thread01a0ffbf-135b retains the qualification/comparison execution; root will re-read the posted exact revised source and supplied original map.

Read correction: an initial guessed qualification.json path returned git-show128. The actual tree lists the receipt and coordinator-shell-observation.json above; no qualification-file absence or missing execution is inferred from the failed guessed lookup. Findings rely on the real receipt's explicit phase/source fields and current PR description.

Exact-head publication findings: #628

FINDINGS at 33aef763bbb43ddeb2851b9c8e060691bcbbaa0e, base 56473e4b840f0e6940c031801d866e7e9bf29baf, following the older 7c9d findings. Scope: current publication claims and actual receipt/source bindings. This is not a whole-code or role/recovery verdict.

The current PR evidence table still labels the coordinator shell check native_proven and says it was “re-run on the final bytes too.” The committed records continue to bind both the live task and coordinator observation to before-B2-repair, worker SHA256 3aa19fa790e661f5142fa316b58473e508f68af6c4f155f0a2fa469177c8a623.

The actual current worker instead hashes to 30f85ea8f8dcbfe443697c79f3c4bb11df6b65f79abb5f0e5ea6aa978e8bdf01, matching the current source closure. Both B2 and B3 explicitly record zero native model tasks started. The separate coordinator-shell-observation.json is unchanged from7c9d, 1,472bytes SHA256 acabe8d2ee66340a99f1d7c3e39d2e99a31c6411c886738bd4c354bedc42c9c6; exact-path git comparison returned0.

Resolve the table's final-byte claim by identifying an existing actual final-byte native observation and its original invocation/output/source binding, if one exists, or by stating the retained live/coordinator observations' pre-B2 scope and classifying the B2/B3 checks as local fixtures/preflight. Keep the retained original shell/transport failures and all original successful observations. This correction does not ask for a silent provider rerun.

Root directly read the current GitHub head/body and committed receipt, hashed the actual current worker and observation artifact, and checked the old-to-current artifact comparison. Native GitHub/checkout/comparison reads returned0. No SDK/model/provider run or new test occurred in this read. Existing-source success remains useful evidence at its recorded source; final writing, blind roles, lifecycle/recovery, backend model/effort and billed cost remain qualification gates in the runtime owner's lane.

[seathatflowsinourveins]

Resolved at head e96879e1cdff. Thank you; the finding was correct.

The final-byte native observation was real but not recorded. The coordinator ran the shell check on the B3 worker at 2026-10-03T04:59:09–04:59:18Z, outside any Codex sandbox, before committing it unchanged at 33aef763. The run's working-tree worker.py:

• hashed 30f85ea8f8dcbfe443697c79f3c4bb11df6b65f79abb5f0e5ea6aa978e8bdf01, equal to the committed blob;
• had an mtime of 04:26:35Z, before the run.

Results from the run's own stdout and native result:

• worker exit 0, status completed, final_response 13;
• one commandExecution (/bin/bash -lc 'ls examples/omniroute-codex-sdk | wc -l', exit 0, 13\n);
• cleanup closed;
• two same-head fixture runs before it, 25 tests OK each.

What changed:

• New record: artifact coordinator-shell-observation-final-bytes.json (sha256 147ba86f…) and receipt key coordinator_shell_observation_final_bytes. The private native result stays outside the repository; only its hash is recorded.
• Kept as they were: live_task and coordinator_shell_observation stay bound to the before-B2 worker 3aa19fa7… with that scope stated. The original failures and observations are unchanged.
• PR table: now separates the before-B2 native observations, the final-byte native observation, and the B2/B3 checks. The B2/B3 checks are classed as local fixtures and preflight (native_model_tasks_started 0).

Backend effort is still unobserved.

[seathatflowsinourveins]

ACCEPT of the publication correction, exact HEAD 68e539f659cce1a01cc216bbd87ef66674b15bbd, base 56473e4b840f0e6940c031801d866e7e9bf29baf. This closes the specific scope mismatch in 33aef findings, with the limits below.

The current description separates before-B2 execution, B2/B3 fixtures and the final-B3 coordinator observation. The four-file delta from33aef changes publication/evidence/registration only. Root independently fetched and hashed the current worker:25,542bytes SHA256 30f85ea8f8dcbfe443697c79f3c4bb11df6b65f79abb5f0e5ea6aa978e8bdf01, matching the final-byte binding. The newly published observer artifact is2,096bytes SHA256 147ba86f3aa68354193872213065e81a6162896a01e684cc1038b2a53d002f08; its exact registry row agrees. Native source/API reads returned0. No provider task was run by this review.

The observer records worker exit0, shell-command exit0, output13 and closed cleanup, attributed to the coordinator's already-existing04:59 observation on the final B3 worker. The receipt entry explicitly preserves the older observations' before-B2 scope and says the original native result remains private. Its hash a7f42b979381c5096517baacd710445e276f15f8ccfbb607de9dbc6d806eafa6 is recorded; root did not read that original. The published fields are a sanitized coordinator observation, not an independent replay or a new run after the findings. File timestamps do not independently establish process start/end. Requested route/effort is recorded; backend effort and provider billing remain unobserved.

This is bounded publication/source acceptance. It does not close writing roles, blind role comparisons, recovery, full-source behavior or SDK qualification. Retain the original shell failures and all earlier before-B2/B2/B3 evidence. The observer's command describes copying a private home with session state removed; the copied-file scope is unspecified in this artifact. A value-free declaration that no credential/auth files were read or copied remains necessary for credential-compliance qualification. No credential violation is inferred here, and root read no private home, auth store or credential value.

Read failure retained and corrected: processing the2.5MB registry through the Contents API returned native0 with omitted content; parsing its empty content failed1. Fetching the exact Git blob 88f0e4bba4d7adc64ea1cb8f39aae4e018381282 through the supported Git Blobs API returned0 and established the observer's registered bytes/hash. No repository/source mutation or provider retry.

ACCEPT of the bounded merge/publication delta, exact HEAD dce7bfb9ff5d83237e8d10429b8f65c844180b8f, base dcae68bd08a191f37ba564eceda9fc4a9d6d4a6e. This carries only the 68e539f6 publication correction to the verified source/registration merge after owner handoff; full SDK qualification remains open.

The merge parents are68e539f659cce1a01cc216bbd87ef66674b15bbd anddcae68bd. All102 non-overlapping retirement paths match main; all76 non-overlapping branch paths match the prior source. Only inventory, its test module and registry overlap. The inventory preserves all50 main inputs and adds exactly three ordinary SDK script locks with explicit uv.lock parsers, yielding51 ordinary/two frozen archives. The workflow/configs are byte-identical to retirement main. Test additions are the prior three SDK hunks, retaining retirement routing/freeze assertions. Original WSL lock remains82,463bytes SHA256 5c51ee65cc477f2c1488a38ff5cad1c0a737f81a5b61bbd70d5edc4d15bfc3bb at the same path; SDK locks are unchanged. No relock, relocation or active-input exception.

The registry retains all187 main receipt rows plus four branch receipt rows, all76 branch-added file rows and the29 convergence paths. Only the two combined inventory/test bindings change against main. Independent scoped integrity rehashed all180 changed-by-either-parent file bindings: zero missing/hash/size mismatches; five new receipt registrations match their payload fields. All native pinned Git/source invocations returned0. This review runs no tests or providers.

The final-byte observer remains a sanitized existing coordinator observation, with private native-result locator and copied-home file scope unresolved as in the prior verdict. Credential-compliance, original-output provenance limits, backend effort/billing and complete roles/writing/blind comparison/recovery are not upgraded. Native sign-ins stay native; no auth/credential files or active client configurations were read/copied, and no source was edited by root. Hosted required checks and fresh merge guards still govern landing.
